Chemical Communications, Royal Society of Chemistry, 2020, 56 (23), pp.3385-3388. ⟨10.1039/D0CC00460J⟩

International audience; A supramolecular solvent based on cyclodextrin (CD) is presented here for the first time. Indeed, a low melting mixture was obtained by mixing levulinic acid and a CD derivative, which retained its inclusion ability in the res

Effect of cyclodextrin and cosolvent on the solubility and antioxidant activity of caffeic acid

Autor: Steven Ruellan, Miriana Kfoury, Sophie Fourmentin, Hélène Greige-Gerges, Chantal Geagea

Publikováno v: Food Chemistry. 278:163-169

Caffeic acid is a natural phenylpropanoid that exhibits various health benefits. However, it suffers from a poor aqueous solubility limiting its application. This drawback could be overcome by complexation in cyclodextrins (CD) or cosolvency. Herein,
